Sealing Around A Hob

[Onoff]

My mates kitchen. Following on from his knocking the hole in the ceramic hob. He's getting there!

 

 

His induction hob (like mine tbh) simply sits with a foam rubber gasket between the underside and the worktop.

 

Should it also then be siliconed?

[Nickfromwales]

Yup.  I mask the worktop with pvc ( insulation ) tape, silicone, wipe with baby wipes, and then de-mask. Once the mask is removed one more wipe up so the silicone is not visible any more.

Follow the manufacturers fitting instructions.They normally just use the foam strip and clips so the hob can be easily removed at a later date .

Also the ventilation is critical on these hobs , follow the instructions or the warranty will be void.

The manufacturers likely won't say to silicon the edge. AFAIC it's a belt and braces to stop debris getting in there. If it's anything like the strip on my induction hob then there's no air flow route through there anyway. 

 

I went a bit ott with mine and routed the top strip to get some air flow through there figuring there's a nominal gap above the doors when they're on:

I don't like to silicone a hob down, your might never get it out in one piece.  but I DO seal the cut edges of the hole in thew worktop so if any water does get through it won't bugger it.

I neat PVA'd my hole... 

 

 

My foam strip is so close to the edge of the glass I really can't see that a small bead of generic silicon would stick the hob down so much that a deft whip around the edge with a blade wouldn't free it.

I wouldnt silicone it simply because if that bead needed cutting out to get the hob back out on wood or laminate worktops, there is a good chance you'd damage the worktops in the process.
